ALBERT A. SAKE, OI SAN FRANCISCO, CALIFORNIA, ASSIGNOR, BY MESNE ASSIGN- MENTS, 0F ONE-HALF T0 RAYMOND G. DOIDGE, OF SAN FRANCISCO, CALIFORNIA.

CABBON-DESTROYJER.

To all whom it ma? concern:

Be it known t at I, ALBERT A. Sales, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Carbon-Destroyers, of which the following is a specification.

This invention relates to a new and use ful composition of matter, which is particularly adapted for removing carbon deposits formed Within the cylinders and valves of internal combustion engines.

My composition consists of the following ingredients combined in approximately the proportions stated, viz:

Kerosene 5 gallons. Commercial henzol 2 Alcohol 3 quarts. Spirits of camphorsfln 1 quart.

These ingredients are to be thoroughly mingled by agitation. The preparation is most effectually mixed at a temperature of g from 65 to 75 F. After it is allowed to stand for about 12 hours, more or less, it is then ready for use. a

The above-named composition forms a freelowing liquid which may be admitted to the cylinders of the engine in any suit able manner, but preferably through the suction side, while the engine is running. This is accomplished by pouring it into the air inlet of the manifold or carburetor. Preferably the preparation is fed through the air intake of the carburetor and mixes and burns with the gas when in a vapor. form.

Specification of Letters Patent.

Application flied July 26, 1913. Serial No. 781,870.

Patented Dec. 1, 1914.

This carbon destroying com osition entering the cylinders. through t e manifold and inlet valves will thus be thoroughly distributed on the surroundin heated surfaces where it will immediate y dissolve and loosen the carbon, permitting this to be discharged through the exhaust valves, and leaving the interior of the cylinder and its moving parts bright and clean, without overheating or injuring the metal in the engine or any other working parts, and all without stopping the engine, or detaching any parts, or disturbing any ad'u'stments.

The proportions o the above mixture are such that the kerosene provides a base, which, while burning, will soften the carbon, the benzol acts as a solvent, the alcohol as a cleanser, and the camphor as a heat reducer. I

Having thus described my invention, What I claim and desire to secure by Letters Patout, is:

The herein'dcscribed composition of mattor for removing carbon from internal combustion engines, consistingof the following mixture in approximately the following proportions: kerosene, 5 gallons; benzo], 2 gallons; alcohol, 3 quarts; spirits of camphor, l uart.

l n testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ALBERT A. SAXE.
